Street lamp controller

Abstract

The invention discloses a street lamp controller which comprises a single chip microcomputer circuit (1), an ultrasonic transmitting circuit (2), an ultrasonic receiving circuit (3), an infrared transmitting circuit (4), an infrared receiving circuit (5) and a street lamp control circuit (6). The street lamp controller has the advantages that whether pedestrians and vehicles are available on a road or not are monitored by ultrasonic sensors, advancing directions of the pedestrians and the vehicles are monitored by the ultrasonic sensors if the pedestrians and the vehicles are available on the road, two street lamp controllers can be communicated with each other via infrared rays, a street lamp controlled by the controller is switched on when the pedestrians and the vehicles are available on the monitored road, three other street lamps in front of the street lamp along the driving directions are sequentially switched on, four street lamps constantly keep working on the road, accordingly, energy can be saved, certain illumination distances can be kept, and the safety of the pedestrians and the safety of the vehicles can be guaranteed.

Description

technical field [0001] The invention relates to a street lamp controller, in particular to a controller for controlling the work of street lamps by monitoring the conditions of pedestrians and vehicles on the highway, which belongs to the field of electrical technology. Background technique [0002] In order to achieve energy saving and practicality, people have designed various types of street lamp controllers. The energy saving methods of these street lamp controllers are all realized by controlling the working hours of street lamps. However, some roads are located in remote locations, there are no pedestrians or vehicles on the roads, and the street lights of the whole road are all on, resulting in a waste of electric energy. Contents of the invention [0003] The problem to be solved by the present invention is to address the above deficiencies, to provide a way to use ultrasonic sensors to monitor whether there are pedestrians and vehicles and the direction of travel ...
